tomcat配置数据源
1、修改tomcat安装目录下的conf文件夹里context.xml文件。注意是在<Context></Context>中。
<Resource name="jdbc/TestDB"
auth="Container"
type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="1000"
username="scott" password="tiger" driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@127.0.0.1:1521:orcl" />
2. 在Tomcat安装目录下的webapps里创建工程SQLtest. (在eclipse中创建项目)
3. 将ROOT下的WEB-INF文件夹整个拷贝至SQLtest中.
4. 修改修改SQLtest\WEB-INF中web.xml,在<web-app></web-app>中添加如下
<resource-ref>
<description>popuserDataSource</description>
<res-ref-name>jdbc/TestDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
此处<res-ref-name>内容应与context.xml中Resource name一致。
5、在WEB-INF中创建lib文件夹,并将sqlserver三个驱动msbase.jar/mssqlserver.jar/msutil.jar(oracle只需要:classes12.jar)拷贝 其中。(2005的只需将sqlserver.jar拷贝就行)
6、 SQLtest下编写jsp测试连接池是否成功,在SQLTest文件夹下创建index.jsp文件.输入内容如下:(注意修改数据库名字.)
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page import="java.sql.*" %>
<%@ page import="javax.sql.*" %>
<%@ page import="javax.naming.*" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<%
Context ctx = new InitialContext();
Context envctx = (Context) ctx.lookup("java:comp/env");
DataSource ds = (DataSource) envctx.lookup("jdbc/TestDB");
Connection conn=ds.getConnection();
Statement st=conn.createStatement();
String sql="select * from emp";
ResultSet rs=st.executeQuery(sql);
while(rs.next()) {%>
您的第一个字段内容为:<%=rs.getString("ename")%>
您的第二个字段内容为:<%=rs.getString("sal")%>
<br>
<%}%>
<%out.print("使用jdbc驱动操作数据库操作成功,恭喜你");%>
<%rs.close();
st.close();
conn.close();
%>
</body>
